Genesis 17:1-7 (NRSV)
1 When Abram was ninety-nine years old, the Lord appeared
to Abram, and said to him, ‘I am God Almighty; walk before
me, and be blameless.
2 And I will make
my covenant between me and you, and will make you exceedingly numerous.’
3 Then Abram fell
on his face; and God said to him,
4 ‘As for
me, this is my covenant with you: You shall be the ancestor of a
multitude of nations.
5 No longer shall
your name be Abram, but your name shall be Abraham; for I have made
you the ancestor of a multitude of nations.
6 I will make
you exceedingly fruitful; and I will make nations of you, and kings
shall come from you.
7 I will establish
my covenant between me and you, and your offspring after you throughout
their generations, for an everlasting covenant, to be God to you
and to your offspring after you.’
